I had to reset my zune, now you can count me out for installing 3rd party apps! I'm going to stick with the ones at the marketplace. I mean don't you think this is the reason these apps aren't at the marketplace?!?!?!?

It needs a reset because of the DRM...
Also, an emulator will never be in the marketplace.
There are quite a number of 3rd party apps that have made it in the marketplace.
Nothing is wrong with these apps, its Microsoft's fault that this happens.
